How well can the model discriminate between positive and negative cases.
sensitivity:true positives / total positives
specificity:true negative / total negatives
AUC: area under the ROC curve

How are model predictions and event rates aligned instrument of risk?
calibration plots, expected calibration error

An Aligned Multi-row equation

\[ \begin{align} y &= \beta_0 + \beta_1 x_1 + \epsilon_1 \\ z &= \gamma_0 + \gamma_1 x_2 + \epsilon_2\\ w &= \delta_0 + \delta_1 x_3 + \epsilon_3 \end{align} \]

The eICU Collaborative Research Database is a publicly available dataset that includes detailed clinical data from intensive care units (ICUs) across the United States (T. Pollard et al. 2019). It provides information on patient demographics, vital signs, and treatments, supporting research on critical care outcomes like mortality and length of stay (T. J. Pollard et al. 2018).
